If you want to take a group photo but there’s no stranger around to take one for you (or you don’t want to hand them your fancy new smartphone), you can use your iPhone’s camera timer to get the job done. This option can be a little tricky to find, so I’ll show you how to find it and how to turn it off when you’re done.

The camera timer is useful for more than just group shots. Photographers sometimes use a three-second delay to make sure the frame is just right before they take a photo, since pressing the shutter button can throw it off. It’s also a really handy tool for getting great photos when the weather is too cold and it’s hard to keep your hands steady. The timer lets you quickly rest your phone on any surface and take photos that way.

To set a selfie timer or a timer for the rear camera on your iPhone, follow these steps:

When you open the Camera app on your iPhone, you’ll see an up arrow at the top of the screen, just below the notch. Tap the up arrow.
